Don’t worry too much after being bitten by a baby, because infants and young children generally contain less bacteria in their mouths, while there is no tetanus clostridium. So if the extent of the injury is small and there is no obvious bleeding, you can apply iodophor or Bactrim and other drugs locally, or you can use iodine to disinfect and then alcohol for deiodination. Do not get water on the local wound and wait for local healing. However, if the wound is large or there is significant bleeding, you need to go to the hospital to see a surgeon for treatment. The doctor will perform regular dressing changes and, if necessary, may also perform debridement and suturing under local anesthesia and give appropriate treatment later. If the patient is a keloid, a scar patch or scar cream should be applied locally to inhibit the growth of the scar, and the injured area should not be exposed to the sun to prevent local pigmentation. The patient should not eat spicy food such as chili peppers and spicy strips, or drink alcoholic beverages within a short period of time after the injury.
